Sorry I'm Late

In a sleepy grumpy voice I said hello. The party on the other end of the line paused for a moment before rushing breathlessly into a lengthy speech.

"Mom, this is Susan and I'm sorry I woke you up, but I had to call because I'm going to be a little late getting home. See, Dad's car has a flat but it's not my fault. Honest! I don't know what happened. The tire just went flat while we were inside the theater. Please don't be mad, okay?"

Since I don't have any daughters, I knew the person had dialed my number by mistake.

"I'm sorry dear," I replied, "but you've reached the wrong number. I don't have a daughter named Susan."
